She has a good personality which lets her face difficulty with cheerfulness. Though she holds feelings for Asbel, she is the type who will not be honest about it. Furthermore she grew distant to those feelings during the long seven years they were separated, making their relationship awkward.
She has strong feelings about being useful to the Lhants, as she has been living with them all this time. Also, as a dedicated healer, she tries her best to help every injured individual she can, usually running straight to trouble. After meeting Pascal, Asbel notes that Cheria acts like a mother for the rest of the girls.
